Real govt and regulatory taxes are *exactly* the same for all airlines. Carrier surcharges (YR YQ) can and do vary a lot. Can be hard to predict YQ YR.
I'm motivated to figure this out! If I can drop the taxes and fees from 36% to 10-15%, that would save us many thousands of dollars which could be potentially put towards nicer hotel, etc.
Is this the right understanding: Taxes are fixed. Fees can vary substantially and are dependent on not just the airline that is operating the segment but also the airline that is issuing the RTW ticket? So to lower tax+fees, assuming I've already chosen low YR/YQ carriers, I'd have to price the itinerary across multiple different issuing airlines?
If so, any recommendations on how to do this? Are travel agents, EF, or the OneWorld RTW site tool able to assist?
SFO-YYZ Availability
For some random dates and Dec 19 when I looked on aa.com did not find a SFO-YYZ non stop. Similarly wikipedia for YYZ does not list non stop flights for AA or AS
So will be SFO-XXX-YYZ. Need to have all segments listed for the OW tool to have a chance of working.
Need to determine before inputting into the OW tool are non stop flights between your airports.
Yes - unfortunately Air Canada is Star Alliance which takes out the main flag carrier. I was looking at SFO-xDFW-YYZ going there and then
EWR-xSEA-OAK on the way back.
Taking into account your other suggestion, something like this with two coast to coast flights within the US:
OSL-MAD-xDOH-KIX,SIN-MEL,SYD-xLAX-oSFO-xDFW-YYZ,EWR-DFW-OAK,NYC-xMAD-OSL
